MOLD.

SPECIFICATION forming part of Letters Patent No. 712,211, dated October28, 1902. Application filed February 11, 1902." Serial No. 93,514.. onmodel.)

To all whom it may concern.-

Be it known that I, EDUARD STRAUCH, a

subject of the Emperor of Austria-Hungary, V,

residing at the city of New York, borough of Manhattan, in the countyand State of New York, have invented certain new and useful Improvementsin Molds, of which the following is a just, clear, and exactspecification.

My invention relates to improvements in making metal castings; and thesame has for its object more particularly to provide an apparatuswherein castings in iron, steel, copper, brass, 860., may be made inlarge numbers and from which the castings when completed may be readilyremoved. These objects above set forth I am enabled to attain by meansof my invention, which consists in' the novel details of constructionand in the combination, connection, and arrangement of parts hereinaftermore fully described and then pointed out in the claim.

In the accompanying drawings, forming part of this specification,wherein like letters of reference indicate like parts, Figure 1 is a topview, partly in section, to illustrate a mold made according to andembodying my said invention; and Fig. 2 is a side view thereof.

In said drawings, A designates the mold, made of iron or other suitablematerial, consisting of two halves or parts B and O. The part B isprovided at its opposite sides with forked projections D D, and the part0 is similarly provided with smaller forked projections E E, in whichare pivoted the ends of the screws F F, provided at their free ends withhand-wheels G G, which are adapted to bear against the outer surfaces ofthe forked projections D D, whereby to hold said parts B C firmlyunited. The part 0 is provided at its rear with a hollow hub orreceptacle H, having at one side a forked projection I.

J denotes a plunger disposed within the re-. ceptacleH and having itsinner surface coinciding with the contour of the interior of the moldcontiguous thereto and adapted to form, together with the portions ofthe mold contiguous thereto, one of said halves or parts of the mold,said plunger being provided with a stem J, which extends through thereceptacle H and its projecting end provided with a slot a, and Kdenotes a lever extending through the slot at in the stem J and havingone end pivoted within the forked projection I and its free end providedwith a handle K.

L denotes a spring disposed upon the stem J intermediate the outersurface of the receptacle H and the lever K, whereby to hold the plungerJ duly in position within the receptacle H.

M denotes theinterior of the mold, into which the metal to be cast ispoured through the opening I) in the top of the part- 0, and 0 denotes avent for the escape of the gases from the interior of the mold.

The operation of the apparatus .is as follows: The parts B and C 'arefirst firmly united by means of the screws F F and handwheels G G, andthereupon the metal is.

poured into the mold through the opening 5 in'the top thereof. As soonas the metal has cooled sufliciently to permit of its removal. from themold the same is opened by partly unscrewing the hand-wheels G G andswinging the screws outward beyond the ends of the forked projections DD. Thereupon the plunger J is forced inward by means of the lever K andthe casting thereby ejected from the mold. To continue the casting, theoperation above described is simply repeated.

It will of course be understood that I do not wish to limit orconfinemyself to the form of the mold, or the form and location of the plungerwithin the mold, or the means for actuating said plunger, as these mustnecessarily be varied with the shapes and sizes of the castings to bemade.

Without, therefore, limiting myself to the details of construction,which may be varied within the scope of the invention, what I claim, anddesire to secure by Letters Patent, 1s

A mold comprising twoseparable parts each provided at its opposite sideswith forked projections, screws pivotally secured within the forkedprojections on one of said parts, handwheels on said screws adapted tocontact with the forked projections of the other part, a receptacleprovided in one of said parts,a forked projection arranged on the outersurface of said receptacle, a plunger disposed within said receptaclehaving a slotted stem extending through said receptacle, a lever extend-Signed at the city of New York, in the ing through the slot in saidplunger-stem and county and State of New York, this 8th day pivotallysecured at one of its ends within of February, 1902. the forkedprojection on said receptacle, and I EDUARD STRAUOH.
